CVE-2026-4955 is a SQL injection vulnerability identified in version 1.3.44 of Shenzhen Ruiming Technology's Streamax Crocus software, specifically in the /OperateStatistic.do endpoint. The vulnerability arises from insufficient input validation of the VehicleID parameter, which allows an unauthenticated remote attacker to inject arbitrary SQL commands. This can lead to unauthorized access or manipulation of the backend database. The vulnerability does not require any privileges or user interaction, making it easier to exploit remotely. The CVSS 4.0 score is 6.9 (medium), reflecting the moderate impact on confidentiality, integrity, and availability, with low attack complexity and no authentication needed. The vendor was notified but has not responded or released a patch, and public exploit code is available, increasing the risk of exploitation. The affected product is typically used in transportation management and fleet monitoring, which may contain sensitive operational data. The lack of vendor remediation and public exploit availability necessitates immediate defensive measures by users of this software. The vulnerability's exploitation could allow attackers to extract sensitive data, alter records, or disrupt service availability, potentially impacting organizational operations and data security.

The exploitation of CVE-2026-4955 can have significant impacts on organizations using Streamax Crocus 1.3.44. Attackers can remotely execute arbitrary SQL commands, leading to unauthorized disclosure of sensitive data such as vehicle tracking information, operational statistics, or user credentials. Data integrity may be compromised if attackers modify or delete records, potentially disrupting fleet management and operational decision-making. Availability could also be affected if injected queries cause database errors or crashes, leading to service outages. Given the critical role of transportation and fleet management systems in logistics, public safety, and commercial operations, such disruptions can have cascading effects on business continuity and reputation. The absence of vendor patches and the availability of public exploits increase the likelihood of attacks, especially from opportunistic threat actors. Organizations may face regulatory and compliance risks if sensitive data is exposed or manipulated. Overall, the vulnerability poses a moderate but tangible risk to confidentiality, integrity, and availability of affected systems.

To mitigate CVE-2026-4955, organizations should implement the following specific measures: 1) Apply strict input validation and sanitization on the VehicleID parameter at the application or web server level to block malicious SQL payloads. 2) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting /OperateStatistic.do. 3) Restrict network access to the Streamax Crocus management interface to trusted IP addresses and internal networks only, reducing exposure to remote attackers. 4) Monitor database query logs and application logs for unusual or suspicious activity indicative of SQL injection attempts. 5) Isolate the database server from direct internet access and enforce least privilege principles on database accounts used by the application. 6) If possible, upgrade to a newer, patched version of the software once available or consider alternative solutions if vendor support is lacking. 7) Conduct regular security assessments and penetration testing focused on injection vulnerabilities. 8) Maintain offline backups of critical data to enable recovery in case of data tampering or loss. These targeted actions go beyond generic advice and address the specific attack vector and operational context of the vulnerability.
